Mobile phone shell and amorphous alloy reinforcement block thereof and manufacturing method of amorphous alloy reinforcement block

Abstract

The invention relates to the technical field of application of amorphous alloy, in particular to a mobile phone shell and an amorphous alloy reinforcement block thereof and a manufacturing method of the amorphous alloy reinforcement block. The reinforcement block is the amorphous alloy reinforcement block made of zirconium-based amorphous alloy, copper-based amorphous alloy, titanium-based amorphous alloy, nickel-based amorphous alloy, palladium-based amorphous alloy or iron-based amorphous alloy. The reinforcement block is 400-600 in hardness, 1000-3000MPa in strength and 2-3% in elastic limit, and is non-corrosive on the surface after 500-2000h salt spray test. Amorphous-alloyed alloy ingot is adopted in the method to manufacture the amorphous alloy reinforcement block through a die casting molding method, a melt spinning method, a suction casting method, a rapid discharge molding method, a continuous casting method or a thermoplastic molding method. The amorphous alloy reinforcement block manufactured by the method has the advantages of high strength, high hardness, high elasticity and anti-corrosion, and the situation that a mobile phone is bent when the mobile phone shell is highly stressed can be avoided.

Description

technical field [0001] The invention relates to the technical field of application of amorphous alloys, in particular to an amorphous alloy reinforcement block of a mobile phone case, a mobile phone case and a manufacturing method thereof. Background technique [0002] At present, the shells of smart phones are mostly made of aluminum alloy through milling. The casing of smartphones tends to be larger and thinner. However, due to the relatively poor hardness and rigidity of aluminum alloys, it is easy for consumers to bend the phone and deform the button hole when using it. In order to cope with this situation, the improvement method adopted by the current smart phone is to use a reinforcing block inside the mobile phone case to prevent the deformation of the mobile phone case. [0003] However, most of the reinforcement blocks in the prior art are made of stainless steel or titanium alloy, and the reinforcement blocks made of stainless steel or titanium alloy have the defe...

Problems solved by technology

[0003] However, most of the reinforcement blocks in the prior art are made of stainless steel or titanium alloy, and the reinforcement blocks made of stainless steel or titanium alloy have the defects of poor strength, hardness, elastic limit and corrosion resistance. When the force is large, the reinforcement block made of stainless steel or titanium alloy is still difficult to prevent the mobile phone from bending

[0004] In addition, the prior art mostly adopts the milling process to prepare the reinforcing blocks. However, due to the complex shape of the reinforcing blocks, the efficiency of preparing the reinforcing blocks by the milling process is relatively low, thus greatly prolonging the production time
